i To aZZ'whmn-it'may concern: r H

Be it known that I, Join: J. RICHARDS, a citizen of the United States and resident of Brookline in the county, oi Norfolk and State of assachusetts, have invented certain new and useful 1m n'oveinents in neserve- Providers for Fuellanks, of which the following is a specification.

This invention relates to liquid fuel tank apparatus such as employed in automobiles and more particularly to means for provid-.

ing-an emergency reserve of gasolene or ether liquid fuel that may he made available vacuum .iuetion system, or by a pressure syshy the operator after the normal supply in the tank is exhausted. In .usua! current practice, the gasolene .is drawn from the. bottom of the tank through. a small pi ie up through the top of the tankeither iy atemo xa'ative in a tank, or by siphon action,-

and the invention is :ulap-ed for any of these systems; .i

y In accordance with my invention l..-proride a pipe for the delivery of the irasolen'e, leading downward from the top,.toward the bottom of thetank, andequipped'f' r adjustment to either of two positions; in one of which it permits the gasolene to be drawn out down to a certain point in the tank only, while in its other position it permits sub.-

s'tantiallyall of-the gasolene to be withdrawn.

1n the illustrative embodiment herein shown this is embodied as a vertical adjustment of. the pipe wherein the pipe may be set normally at a predetermined distance above the bottom of: the tank to draw-the gasolenej therefrom only down to a redeter nined point above thetank bottom, eavmgf a certain definite reserve .supply: of gasolene' whieh'may be drawn upon in emergency by adjusting the pipefar't ier downwarchor so that it is adaptedto draw an of the re mainder-of the li .uid fuel from the tank The foregoing an other objects and ad- .vantages. ofjthe invention will more v fully.

n pear from the. followin detailed-descrip di and the distinctive teatures of nnvelt'y' will thereafter be; pointed out: in. :the ap pended cllims.

. 1 1g. 3 is a transverse section on line of Fig. 2, and V I Fig.4 Isa section similar to Fig. 3, but

showing the pipe moved out of its locked-p0' sition.

This pipe has an. elbow 11 at its end connecting it withavertical pipe 153 leading down into the tankuand"slidalily fitted through a bushing p,lu; ..13 which may be equipped with an -externallythreaded f nipple 13" as usual for securing it -ina.

In apeoi'dniice with my invention, the pipe 12 is fitted tor sl ding adjustment throu h' 1 the plug 13 and 1t is.equippedtoward its upper end with a groove 14 w iich is engaged by'a split spring" ring 15 housed in an annn the liottoin of t is tank, and so as to leave a tank after it is drawn out down'tosuehf certain reserve supply R of gasolene in the: .1

as i ry 'witha ealms;. -bll1ty 0f convenient.-manualledjust i imp m ing such reserve at willf. 1t will lie under-" stood that the pipe connection f 1-1 frointhe E1pe12 is, in usual practice, of a fairly flexi le jnatnre, so that the" described vertical. gmoveme'rlt of the pipef12 ispermitted without interfering with connection; Tum, aware that the invention may be embodied: in other Ispecific-f-forms without-departing from the. spirit or essential attributes there'- of, and I therefore desire the resent embodiment to be considered in a] respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the sec e of the invention aving described my invention, what I Patent is: 1 1

claim as new and desire to secure by Letters 1. The combination with a fuel tank, of a delivery conduit leading from the top thereof to a motor, comprislng a portion leading from the lower part oiv the tank with a member thereof adjustable from the top of the tank constituting in itself themeans of adjustment," and arranged in one position of adjustment to leave a predetermined reserve in the tank, and in anotherposition of adjustment to withdraw such reserve for utiization in emergency.-

2; The combination with a fuel tank, of a delivery conduit leading from the top thereof to a motor, with an upper portion thereof constituting an operating element and com prising a portion extending downward to near the bottom of the/ tank including an element equipped to be adjustably set in either of two positions, with an arrangement so that in one position of its adjustment the withdrawal of fuel ceases at a predetermined level above the bottom of the tank, and in another position of adjustment the entire contents of the tank may be withdrawn.

3. The combination witha fuel tank, of av combined fuel delivery and actuating means comprising a pipe connection from the top of the tank to a motor, and extending straight downward from the tank top into the lower part of the tank, said means operable at the top of the tank to cause a draft of fuel from either of two levels, of the body of fuel in said tank.

Q4. The combination with a fuel tank, of a grooves, said tank top having means delivery pipe leading from the top thereof to a motor and with a movable supply connection extending straight downwardinto the'lower part of the tank from the tank top, said supply sion in substantlal alinement therewit and operable at the top of the tank to move said connection and thereby cause it to draw fuel from either of two levels of the body of fuel inlthe tank. 7

5. The combination with a fuel tank,of a delivery conduit leading therefrom to a motor, comprising a single pipe extending verticallydownward through said tank to near the bottom thereof with its lower end continuously open and slidably mounted in the top of said tank withprovision for predetermined vertical s ng adjustments therein whereby the lower inlet end of said pipe ma be located either at the bottom of said tan or a predetermined distance thereabove at will sufiicient to leave a required reserve in the tank, the top of the tank equipped with means for frictionally and yieldingly engaging said pipe to hold it in a given position.

6. The combination with a vertical tank connection having rovi of a delivery conduit leading therefrom comprising a pipe extending from the top of the tank downwardwith an inlet end near the bottom thereof, the top portion of said pipe having a slidable fitting in the tank,top.and equipped with spaced apiart or yieldably engaging said grooves to hold the Jpipe with its lower end a predetermined distance above the bottom of the tank ermit ting manual sliding adjustment of said pipe so that said] inlet will. be located approxh mately at the bottom of the tank at will.
